Running through La Geria is unlike any other race you'll do on the islands. The course threads between the vines, each one sunk in its own little crater of black volcanic gravel and shielded by a low stone wall, so you're picking your way across a landscape that looks half-farmed, half-lunar. There's a long route and a shorter one, plus a kids' race, and a couple of camels usually turn out along the way as a nod to how the wine was once worked here.
Afterwards the parallel wine festival is where most people end up: island bodegas pouring tastings, food from local producers, music, and a fair bit of standing about in the sun comparing times. Entry to the run isn't free, and money goes towards the Save La Geria conservation effort. It tends to land in June each year, with online registration opening ahead of the next edition.
